Application filed April 11, 1918; Serial No. 227,922.

' To all whom-it may concern:

Be it known that I, JAMES HASLAM, a citizen of the United States,residing at Sioux: Falls, in the county of Minnehaha and State of SouthDakota, have invented certain neW and useful Improvements in Tatting-Shuttles, of which the following'is aspecification.

This invention relates to certain new and useful improvements in atatting shuttle and. it aims to provide a simplyjconstructed shuttleembodying a rotatable bobbinwith means for rotating the same threadthereonQ Further, the inventioniresides in an improved lock forreleasably holding the bobto. easily wind the bin against unwinding,which lock is revention the barrel or body 1 of the shuttle is providedwith a pointed nose or end 2 that may be integrally formed therewithalthough it is here shown as separable therefrom. The opposite end ofthe barrel is in ternally screw threaded to receive a combined lockingand closure plug 3 which has its inner end formed with an annular seriesof ratchet teeth 4 for interlockingly meshing with similar teeth 5 thatare formed on the adjacent end of the bobbin or spool 6.

This bobbin is spool-shaped and is arranged within the chamber of thebarrel for longitudinal movement therein. The heads 7 serve as bearingsfor the spool both in its longitudinal and rotative movements, anadditional bearing being provided by a shaft 8 which is passed throughan opening 9 in the ratchet nut or plug 3 and fixedly carries thebobbin. A coiled expansion spring 10 is seated in a well or recess 11,formed at the inner end of the bobbin chamber, and bears outwardlyagainst the opposing end of the bobbin to resiliently and yieldably holdthe ratchet teeth of the bobbin in interlocking mesh with the teeth ofthe ratchet nut. The spring receives the projecting end of the shaft 8for being steadied and guided thereby.

A depressible knob 12 is carried by the outer end of shaft 8, the samebeingguidingly received within a counterbore 13 in the nut 3. When it isdesired to wind thread on the bobbin the knob is turned. in thedirection in which the cooperating ratchet teethiwill yieldingly pass orride by each other, the bobbin being fixed 0n the shaftS. I v I Inpractice, the. thread is passed through a longitudinal slot 14 in thebarrel 1 and is wound on the bobbin merely by revolving the handle knob,the spring maintaining a locking relation between the ratchet teeth sothat normally the bobbin is locked against unwinding rotation.v

Unwindingv motion may be imparted to the bobbinwhen the knob, isdepressed to disengage the intermeshing ratchet teeth from one anotherbut this operation is not always convenient in tatting, therefore, the

slot 14 is made sufficiently long, extending beyond the inner end of thebobbin, so that;

the thread may be pulled toward the pointed end 2, whichexertiombyreason of the bobbin being held against rotation, will slidethe bobbin and its teeth away from or out of engagement with the ratchetteeth of nut 3 and then revolve said bobbin and feed out the threaduntilthe tension on the latter is less than that of the spring when theratchet teeth will be reengaged with each other. Therefore, all the useris required to do, in order to pay out additional thread, is merely topull the thread longitudinally of the shuttle body toward its nose,which releases the ratchet lock and permits freev rotation of thebobbin.

The thread is easily wound onto the bobbin, and the unwinding is alwaysunder the control of the user. The shuttle body may be made of any lightor desirable material which may be given a smooth and neat finish, andalthough the construction has been specifically described andillustrated, changes may obviously be resorted to as fall within thescope claimed.

What is claimed is:

1. A tatting shuttle comprising a cylindrical barrel having one endpointed and its opposite end internally screw threaded, said barrelhaving a bobbin chamber and a longitudinal slot through its side, aratchet nut threaded in the opened end of the barrel and formed with anaxial opening and a counterbore, the opposite end of the chamber beingformed with a well, a spring located in the well, a bobbin spoolrotatably disposed in the chamber andprovided on its outer end withratchet teeth interlocking with the teeth of the ratchet nut, a shaftpassing through the opening of the latter and fixedly carrying thebobbin spool, and a knob carried by the outer end of the shaft andretable and slidable in the chamber, a ratchet means in one end portionof the barrel, and cooperating ratchet .means on the bobbin normallyinterlocking with the first ratchet means to prevent unwinding movementof the bobbin and releasable from said first ratchet means to permitunwinding move ment of the bobbin on moving the bobbin longitudinallywithin the chamber, the slot in said barrel extending below the threadCopies of this patent may be obtained for wound on the bobbin to permitthe latter being moved longitudinally by pulling the thread in the samedirection.

4. In a tatting shuttle, a barrel having a bobbin chamber formed with alongitudinal slot opening through its side, a bobbin rotatable andslidable in the chamber, means permitting free winding movement of thebobbin and preventing unwinding movement thereof, and manually operablemeans for moving the bobbin longitudinally in its chamber whereby thefirst means is rendered inoperative to permit free rotation of thebobbin.

5. A tatting shuttle comprising a cylindrical barrel having one endpointed and its oppositeend internally screw threaded, said barrelhaving a bobbin chamber and a longitudinal slot through its side, aclosure member en aged in the opened end of the barrel and formed with aratchet part on its inner end, the opposite end of the chamber beingformed with a well, a spring located in the well, a bobbin spoolrotatably disposed in the chamber and having its outer end formed withratchet teeth for engaging the ratchet part of the closure member, and ashaft extending through the closure member to provide means fordisengaging the ratchet teeth.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JAMES HASLAM.
